| 主权项 | 1. A method for network-based positioning of a mobile device, the method comprising: selecting a first set of access points (APs) to take first positioning measurements from the mobile device, wherein selecting the first set of APs comprises: designating a central AP,radially dividing an area extending from the central AP into a plurality of sectors, andselecting, as the first set of APs, one or more APs from each of the sectors; obtaining the first positioning measurements from the first set of APs; selecting, based on the first positioning measurements, a second set of APs to take second positioning measurements from the mobile device; obtaining the second positioning measurements from the second set of APs; and determining a location of the mobile device based on the first positioning measurements and the second positioning measurements. | ||
